The authors investigate linear transceiver design in uplink (UL) coordinated multipoint transmission and reception (CoMP) multiple-input multiple-output (MIMO) systems with joint detections. A two-stage design algorithm is proposed by exploiting the technique of interference alignment, optimising the structure of the effective channel and employing power loading, with the goal to achieve high throughput...
An efficient interference alignment (IA) aided transceiver design algorithm for uplink (UL) coordinated multipoint (CoMP) systems is proposed to mitigate interference. We use the block QR decomposition (BQRD) to resolve the interdependency of precoders among user equipment (UE) through the successive interference cancellation (SIC) technique. To further improve the efficiency, an additional constraint...
Interference alignment (IA) in uplink coordinated multipoint (CoMP) has been proved to be able to improve the performance in next generation mobile cellular systems. In this paper, an efficient codebook-based Max-SINR IA aided uplink (UL) CoMP scheme with full cooperation at the receiver is proposed. Compared to conventional IA, codebook-based IA requires less feedback information and maintains the...
The demand for high data rate and uniform throughput for cellular user terminals in the cell coverage leads to a new uplink coordinated multipoint (CoMP) transmission/reception technique proposed by the 3GPP LTE-A system. In this paper, we incorporate the recently proposed interference alignment (IA) techniques in uplink CoMP to improve system capacity by leveraging the full cooperation and information...
